Welding Neck-ASME Sec I & Sec II

Welding neck safety valves designed under ASME Section I are typically used in high-pressure and high-temperature applications, such as boilers and pressure vessels. Here's an overview:

1. Design Features:
   • Welding Neck Connection: These valves have a long, tapered neck that is welded directly to the piping system, ensuring a strong and leak-proof connection.
   • ASME Section I Compliance: They are built to meet the stringent requirements of ASME Boiler and Pressure Vessel Code (BPVC) Section I, which governs safety valves for power boilers.
   • Materials: Commonly made from durable materials like carbon steel or stainless steel to withstand extreme conditions.
2. Applications:
   • Used in steam boilers, superheaters, and economizers.
   • Ideal for systems where high reliability and safety are critical.
3. Advantages:
   • Durability: The welding neck design provides excellent mechanical strength.
   • Safety: Complies with ASME standards to ensure safe operation under high pressure.
